- Semisynthetic Aminoglycoside Antibacterials. Part 9. Synthesis of Novel 1- and 3-Substituted and 1- and 3-epi-Substituted Derivatives of Sisomicin and Gentamicin from the 1- and 3-Oxo-derivatives
-
The conversion of selectively protected gentamicin and sisomicin derivatives into the 1- and 3-oxo-compounds by reaction with 3,5-di-t-butyl-1,2-benzoquinone is described.By application of suitable reductive techniques these oxo-aminoglucosides have been converted into novel 1- and 3-epi-, 1- and 3-deamino-1- and -3-hydroxy-, 1- and 3-deamino-1- and -3-epi-hydroxy, and 1-deamino-derivatives.A study of the 13C n.m.r. parameters of the 1-epi- and 1-deamino-derivatives has led to the assignment of novel solution conformations for these new aminoglycosides.
